The organization of the paper is as follows. After a brief review of baryon magnetic moments at tree-level in Sec. , the discussion is focused on the computation of one-loop corrections in Sec. ; complete although rather long expressions are thus provided for contributions of orders \(\mathcal {O}(m_q^{1/2})\)  and \(\mathcal {O}(m_q\ln m_q)\)  in Secs. REF  and REF , respectively, followed by their respective analytical comparisons with heavy baryon chiral perturbation theory results. The issue of explicit symmetry breaking is reviewed in Sec. , based on the analysis of Ref. [1]}. Gathering together all partial results allows one to carry out a numerical analysis to determine the free parameters of the theory, by making a least-squares fit to the available data [2]}. Results are presented in Sec.  and some closing remarks are provided in Sec. . The paper is complemented by two appendices where the complete baryon operator structures involved in the analysis are provided for completeness.
